Application f led December 26, 1916. Serial-No. 138,999.

To all whom may concern.

Be it known that I, THOMAS L. FAWIQK,

' a citizenof the United States of America,

' and which are illustrated in the accompanying drawings, in which Figure 1 is a plan view of my improved tractor frame and housing for the mechanism thereof, with parts removed or broken away; Fi 2 is a side elevation of the same, with t e addition of certain mechanical elements, and

Fig. 3 is a detail view of the housing-seat for the boxing of the steering-gears.

Similar numerals of reference denote corresponding parts throughout the several views.

Referring to the drawings, the numeral 1 denotes the U-shaped frame of a tractor, formed from a bent channel-bar, or bar of any other desired cross-section. A crossbeam 2 connects the members of said frame a little forward of their middles, and has its ends secured thereto by bolts 15. This crossbeam may be or not be integral with the motor-housin 3, but is preferably cast integral therewit in order to insure proper rigidity and prevent any relative movement between the parts under the shocks of use.

The rear apart of the motor-housing .3 has oppositelyirected horizontal lugs or arms 4 mounted and secured fixedly u on therear ends of the members of the ame 1 by means of bolts 16.

Upon the rear open face of the motorhousing 3 is secured a housing 5 to contain the clutch-mechanism, said housing 5 having an integral rearward extension6 containing the transmission-gearing, as also a chamber 9 for the drivingears of a transverse shaft carrying a belt w eel 12,. said shaft being seated in a lateral boxing 11 of said'housing. Said housing also contains a chamber 10 to receive worm or other gearing formhousin ing part of the driving-mechanism for the shaft 14 of the traction-wheels 20. The

housing-part 10' has oppositely-directed hollow parts 13, which serve to receive the axles- 14, and the terminal part of the housingpart 10 is in the form of anintegral cylindrical casin for a friction-drum brake.

On one side of the housing-part 6 is a laterally-directed open seat 7 upon which is secured a housing 8 adapted to'receive the steering-gears of the steering-wheel shaft 18. The forward part of the U-shaped frame 1 may be supported on one or more carrying wheels (not shown) suitably connected operatively with the steering-mechanism of the tractor.

In this application I do not particularly I Y show, nor do I claim, special features of the mechanism of the tractor, preferring-to reserve such for other applications, but confine myself to the new and improved frameand structures therefor.

The -shaped frame 1 is not only less expensive to construct thanmulti-part frames, but ismore durably rigid, yet weight consistent with its strengt The motor-housing 3 is in one piece, and so strongly mounted on and connected to the frame lat widelyseparated locations as to be ableto resist the rudest shocks without relative displacement, and has a minimum of minimum number of openings or joints, which renders it practically dust-proof.

The other housing-part 5610, and the steering-gear boxing 8 are so alined relatively to the motor-housing as to make one rigid casing for all the mechanism of the tractor, easily assembled orfdisassembled, and havinglarge openings to permit in ection, removal or repair of the elements 0 the mechanism, without necessity of demounting any part of the housing itself.

The boxing 19 for the band-brake, also the boxing 8 for the steering-gear are in free communication with oil-filled parts of the housing 6-10, which insures complete lubrication of the moving parts therein. This obviates any necessity for independent lubrication of the steering-gear.

It is also to be understood that conside able variations or modifications of the parts of my improved device maybe effected, without, however, departing. from the principles of my invention, or from: the scope of its protection.

1 Having described my invention, what I claim as new, and desire to secure by Letters gear elements;

Patent, isv a l. in combination, a U-shaped frame, a housing for mechanism rigidly mounted on the members of said frame, and alined communicating housing-compartments for other connected mechanism in communication with said housing and mounted on the rear part I of said first-mentioned housing rigidly.

2. In combinatiomn U-shaped frame, and alined housing-parts for-moving mechanism mounted on said frame in medial alinement therewith to extend rearwardl therefrom, said housing having laterally-directed housing compartments for laterally directed mechanisms operatively connected 'to the mechanism in the main housing,

3; in combination, a frame, a housing to independently receive a motor mounted thereon, another. single-piece housing rigidly secured to the rear part of said motor-housing opening directly thereinto and having compartments adapted to receive clutch: mechanism, transmission-gearing, belt-wheel gearing, and traction-Wheel mechanism, in

the order named,- and a boxing removahly secured to the latter housing opening directly thereintoand adapted to receive steeringi. in combination, a housing to independently receive ajmotor, another housing for neaeee mechanism mounted rigidly upon said moter-housing in communication therewith, and a steering-gear 'bomng mounted upon one side of said second-mentioned housing,

mec anis mounted rigidly upon said motorhousing in communication therewith, a steering-gear boxing mounted upon one side of said second-mentioned housing, and a bearing-hox for a belt-Wheel shaft mounted upon the opposite side of said second-mentioned housing, both said hoxings having openings and said housings having openings registering therewith;

6. In combination, a hollow housing for moving mechanism, and a boxing to'conta'in steering-gear elements detachably secured thereto and in communication therewith, 1 said housing and said boxing being formed to receive and retain a communicating sup-= ply of a fluid lubricant immersing'said mechanisms.
